Definitions

  • This invention relates to antenna actuator mechanisms and more particularly to support structures for rotatable storage drums used in antenna actuator mechanisms.
  • Another object of this invention is to provide an improved power antenna actuator structure wherein a cable storage drum is driven in rotation by a worm and worm gear drive and wherein a locating support rib contacts the storage drum adjacent the mesh and worm gear to prevent movement of the storage drum in a direction transverse to the worm.
  • FIG. 1 is a side elevational view of a power antenna and drive mechanism
  • FIG. 2 is a sectional view taken along line 2--2 of FIG. 1.
  • an antenna drive mechanism generally designated 10, having a housing 12 and a cover 14.
  • a conventional electric motor not shown, is disposed in the housing 12 beneath cover 14 and has an output shaft 16 which drives a worm 18.
  • a reaction switch 20 is operatively connected to the output shaft 16 and is preferably constructed in accordance with the reaction switch shown in U.S. Ser. No. 900,051, filed Apr. 26, 1978, and assigned the assignee of the present invention.
  • a drum assembly houses a cable 24 which is connected to drive a conventional telescoping antenna, not shown, housed in a mast jacket 26.
  • the drum 22 as best seen in FIG. 2, is comprised of an outer member 28 and an inner member 30 which are similar in construction to the members shown in the drive drum disclosed in U.S. Ser. No. 938,752, filed Sept. 1, 1978, now U.S. Pat. No. 4,181,268 and assigned to the assignee of the present invention.
  • the outer member 28 has formed on the outer periphery thereof, a worm gear 32 which meshes with the worm 18.
  • the outer member 28 has an inner cylindrical component 40 which is rotatably mounted on and slightly spaced from a cylindrical member 42 formed integrally with the housing 12.
  • the cable 24 is stored in the space formed between the frustoconical surfaces 34 and 36 and is drivingly connected to the inner member 30 such that when the drum assembly 22 is rotated by the electric motor, the cable 24 will be extended from or retracted into the storage drum depending upon the direction of rotation of the electric motor.
  • the cover 14 is secured to the housing 12 by a plurality of spring clips 44 and a rivet member 46.
  • a post 48 is formed integrally with the cover 14 and has rotatably disposed thereon a gear member 50 which is maintained in longitudinal position on the post 48 by a fastener 52.
  • a spring washer 54 is disposed between the cover 14 and the gear member 50 and imposes an axial load between the gear 50 and the fastener 52 such that the gear member 50 will not be freely rotatable but must require a slight input force for rotation.
  • Rotation of the gear member 50 is accomplished by a single tooth 56, shown in phantom outline, which tooth 56 is formed integrally with the inner member 30 such that as the inner member 30 makes one complete revolution, the gear member 50 will be moved one tooth space in either a clockwise or counterclockwise direction depending upon the direction of rotation of the drive drum 22.
  • the single tooth 56 and gear member 50 cooperate to impose a resistance to the rotation of drum assembly 22, as described in U.S. Ser. No. 962,922, filed Nov. 22, 1978, now U.S. Pat. No. 4,190,842 and assigned to the assignee of the present invention.
  • the cover 14 has a rib 58 which extends axially into the storage space provided between surfaces 34 and 36.
  • the rib 58 is arcuate in shape and extends between the radial lines 60 and 62 shown in FIG. 1.
  • the rib 58 is in an abutting relationship with the upper portion of surface 34 at a position substantially opposite the mesh point 64 between worm 18 and worm gear 32.
  • the driving action between the worm 18 and worm gear 32 has a reaction force which tends to separate the worm 18 from worm gear 32 in a direction transverse to the axis of worm 18.
  • the rib 58 prevents movement of the drum assembly 22 in a direction transverse to the axis of worm 18.
  • the cylindrical component 40 has the inner diameter sized thereof to provide a clearance with the cylindrical component 42.
  • the clearance between cylindrical component 40 and cylindrical component 42 will permit the drum assembly to move in a direction longitudinal to the worm 18, however, this movement will not affect the operation of the antenna actuator.
